Answer:
The numbers are 2, 4, 6 and 8
Step-by-step explanation:
let the four numbers be x, y, z and l respectively
then:
x+y+z+l
(z+l)–6=4x
since they are all four consecutive even integers
then y=x+2
z=y+2=x+4
l=z+2=x+6
since (z+l)–6=4x
then ((x+4)+(x+6))–6=4x
2x+4=4x
4=4x–2x
4=2x
2=x
200+15x=320
and then the actual answer to the question is 8 lawns.
The equation is -5x = 4
x = -0.8
A is false but R is true (the mean of the last 3 values is not 8 since x=7)
The answer is
X=7
